columnDefinition ::=
    'NAME' '=' columnName ',' ( 'PLAIN' '=' plainColumnName )? 'CIPHER' '=' cipherColumnName ','  'TYPE' '(' 'NAME' '=' encryptAlgorithmType ( ',' 'PROPERTIES' '(' 'key' '=' 'value' ( ',' 'key' '=' 'value' )* ')' )? ')'
    
tableName ::=
  identifier

columnName ::=
  identifier

plainColumnName ::=
  identifier

cipherColumnName ::=
  identifier

encryptAlgorithmType ::=
  string

Example

Create a encrypt rule

CREATE ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id, CIPHER =order_cipher,TYPE(NAME='MD5'))
),QUERY_WITH_CIPHER_COLUMN=true),
t_encrypt_2 (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id, CIPHER=order_cipher,TYPE(NAME='MD5'))
), QUERY_WITH_CIPHER_COLUMN=FALSE);
